How is the Tissue Prepared for Histological Examination?
After surgical resection, the tissue is sent to the pathology lab, where it undergoes several steps:
Fixation: The tissue is preserved using chemicals like formalin to prevent decay. Embedding: The tissue is embedded in a solid medium, usually paraffin wax, to facilitate slicing. Sectioning: Thin slices of the tissue are cut using a microtome. Staining: The sections are stained with dyes like hematoxylin and eosin to highlight cellular structures. Microscopic Examination: A pathologist examines the stained sections under a microscope.
